SPECIFICATION forming part of Letters Patent No. 278,741, dated June 5, 1883. Application filed December 30, 18.82. (No model.)

To @ZZ whom it may con/cern: l

Be it known that I, FRANCIS J. RENCHIED, a citizen ofthe United States, residing at Detroit, in the county oi IVayne and State of Michigan, have invented certain new and' useful Improvements in Lubricators; and I do hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the avt to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or iigures of reference marked thereon, which i'orni a part of this specification.

My invent-ion relates to improvements in lubricators'; and it pertains to that class in which the feed of oil is ascertained as it passes upward through water in a glass indicator-tube.

The object oi' my invention is to simplify the construction and diminish the number of parts ofthe lubricator, whereby the expense oi' construction is reduced.

My invention is further explained by reference to the accompanying drawings, in which Figure l represents a vertical section. Fig. 2 is a side view. Figs. 3 and 4 are detail views.

Like parts are represented by the same reference-letters throughout the several views.

The condensing-chamber A, neck B, connecting-trunk G, steam-tube D, and glass cage E are east in a single piece, and the oil-receptacle F and glass cage G are also cast in a single piece. Thesetwo pieces are connected together by the screw-joint H upon neck B. Communication between the oil and water chambers is closed by the plug I, which plug is located at the lower end of said neck B, while the connecting-trunk C and the upper glass cage are 'formed at the upper end of said neck. To the lower side of said plug I is a curved U -shaped tube, J, through which water is conducted from the condensing-chamber into the oil-receptacle.

U is a valve for regulating the ilow of water from the condenser to the oil-receptacle.

' The trunk C is provided with two passages, c and b, one connecting directly with the condensing-chamber A, and the other with the upper glass cage, E.

L is the oil-filling hole.

M is a glass indicator-tube, which is supported by the cages N and O. (Shown in Fig. 3.) The object oi' the glass tube M is to show the quantity ot' oil in the receptacle F. The glass tubeil/I and the supporting-cages may, however, be dispensed with, if desired7 and the oil-filling hole formed in the side or top ofthe oil-receptacle, as shown in Fig. 2.

The passages to and i'rom the glass tube K are respectively governed by the screw-valves P I. The knobs of the valves I) I) are made of wood or other poor conductors of heat,.to prevent contact of the hand with the metal. The knobs are formed of two disks, It and S, upon one oi' which is a stud, T, which is inserted through an opening inthe end of the valve-shank,when the disk, which is provided with a central opening, is then pressed upon. said stud, and thus retained upon the opposite side of said valve, as shown in Fig. 4. f My lubricator operates asv follows: W'hen the boiler is made steam-pressure, the valves U and I are closed to exclude steam while iilling the oil-receptacle F., AThe oil-receptacle being filled, said valves U and I? are opened, when steam enters the condensing-chambers through passage a and steam-tube D, when it condenses and the water passes into the oilreceptacle F through tube J. The water thus entering floats the oil, causing it to escape, drop by drop, up through glass tube K, from whence it passes through passage I) into the steam-pipe. f

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

I. The chamber A, neck B, trunk C, and glass cage E, cast in a single piece, said trunk being provided with separate steam and oil ducts and formed in line with vthe said glass cage E, at the upper end of the glass tube K, in combination with the oil-receptacle F and glass cage G, said cage G being formed at the upper end oi' said oil-receptacle, substantially as set forth.

2.. The combination of reservoir A, neck B, trunk C, stopper I, curved tube J, and valve U, said stopper I being formed at the lower end of said neck, below said trunk, the length v of said neck being such as to permit said side glass to be interposed in the spaee between In testimony whereof I affix my signature in. I

said trunk and the top of said oil-receptacle, presence of two witnesses. Y substantially as set forth.

T 3. The Combination, with the oil-reservoir FRANCIS J' REA CHARD' F, stopper I, and curved tube J, of the glass Vitnesses: indicator-tube M, provided with cages N and J OHN'SEBERT, o, :ma Oil-thing 1101@ L, as set forth. I GEORGE GATES.
